Last night's dream

Last night (more accurately, this morning) I had a dream that I saw my dad.  In this dream, I was back at my job where I worked with him.  I had turned around, and there he was, the man I knew before he was ill.  He looked great and there were no oxygen tanks.  In my dream, I began to cry because I knew he really wasn't there.  I began to walk towards my desk and my dad's best friend/boss came out of his office to ask why I was crying, and I cried even harder because I knew he wasn't really there either.  I was trying to explain to someone that I had seen them so vividly even though I knew they weren't there...and that's when I woke up.  It was one of the very few dreams I've ever had where I wake up and I'm either actually crying or very near to doing so.  While seeing my dad look so good was in some ways very peaceful, this particular dream was more upsetting than peaceful.  Frotunately, I was able to fall back to sleep and it wasn't how I began my day.  I sure do miss that man.
